CONTAINER.

Specification of Letters Patent.

Patented May 15, Torr.

Application filed July 14, 1915. Serial No. 39,869.

To all whom it may concern Be it known that I, Enxics'r O. lVImnLocK,

a citizen of the United States, and a resident of Chicago, in the countyof Cook and State of Illinois, have invented certain new and usefulImprovements in Containers, of which the following is a specification. IThe invention relates to containers and more particularly to closuresfor containers or cans that are formed wholly or in part of paper orfibrous material. The invention seeks to provide improved means forsecuring the container cap or cover in place. A further object of theinvention is to provide improved means for sealing the can or containerin water tight fashion so that the same can be sterilized and used forhot liquids, as Well as other purposes, without leaking'or loosening theparts. Further objects are to provide improved sealing means that arereadily detachable to afford access to the contents of the containerwithout the use of instruments or tools; to provide means for,reinforcing and protecting the ends of the can or container from injury;and to provide improved sealing means of such a character that anyattempt to open or tamper with the container will be readily detected.

The invention consists in the features of improvement hereinafter setforth, illustrated in the preferred forms in the accompanying drawingsand more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of a round canorcontainer with parts of its body portion and cap removed to moreclearly illustrate the improved sealing means.

Figs. 2 and 3 are detailed plan and sectional views illustrating themanner of applying the in'lproved sealing or binding strip. Figs. 4 and5 are detailed sectional views of modifications.

The improved binding or sealing strip can be applied to cans and othercontainers of any desired shape and havi'ngvariously arranged lippedopenings. In Fig. 1 a cylindrical can or container is illustrated. Thesame comprises a cylindrical body portion A preferably formed of heavypaper or pasteboard and open at its ends. Paper or cardboard caps orcovers B having outturned flanges B fit snugly within the open ends orlips of the body portion A. A binding strip (7 is formed of soft,annealed or non-elastic metal and is preferably formed of soft annealedwire and is bent back and forth upon itself to form a plurality ofconnected, overlapping loops. The loops are bent transversely midwaybetween the edges of the sealing strip, preferably to the form shown inFig. 3, and the strip is then placed over the flange B of the cap orcover and over the edge or lip of the body A of the container, as shownin Figs. 2 and The opposite end portions of the loops are then pressedor firmly clamped upon'the flange and edge or lip of the body portion,as shown in Fig. 1, to thereby secure the cover 111 place.

In the preferred embodiment of the invention, the can body A and coverBare formed of waterproofed paper or other fibrous material, and theloops are pressed or clamped against the cover flange and edge of thebody portion tosuch an extent that they are embedded to a greater orless degree in the fibrous material of which these parts are made, tothereby form a watertight joint between the can body and its cover. Ifdesired, the tool employed for compressing the looped sealing strip canbe provided with means for forming corresponding offsets in the clampedportions, as indicated at C in Fig. 4 to thereby provide additionalsecurity in the joint between-the cap or cover B and body portion A.

The improved metal binding strip, as stated, is formed of soft. annealedor nonelastic metal and is preferably formed of soft annealed wire andis flexible so that it can readily be applied for securing the caps orcovers of different shapes in place. If either the body portion of thecontainer. or the closure therefor, or both, are formed of 'aterproofedfibrous material, the binding strip serves to form an effectivewater-tight joint without necessitating the use of adhesive sealingmaterial. l urthermore. the sealing strip can be readily detached topermit the removal of the cap or closure and thereby afford access tothe contents of the container without necessitating the use of tools toopen the same. For convenience, in detaching the retainer strip, thelatter is preferably formed of a single continuous piece of wire and atone end is provided with an extension I) which can be convenientlygrasped to remove the sealing strip. In the form shown, the part Dextends'inwardly over and in snug contact with the face of the cap orcover 13. When once removed, it would be extremely difficult to replacethe same without leaving evidence of the fact that it had been removed,since the application of the sealing strip indents the fibrous materialof Which the body portion or cap, or botlnare formed, and since it wouldbe practically impossible to open the compressed lips and reapply thesame neatly and in exact alinement With such indentations. The sealingstrip also serves to reinforce and protect the end portions of the papercan or container.

In the form shown in Fig. 5, the container A is formed of glass or thelike. Its mouth or opening is provided with a beaded lip a, an inwardlyproject-ing shoulder a and a recess a between the loop and the shoulder.In this form, the sealing strip C serves to force the edge or flange Bof the paper cover B into the recess a so that the cover is secured inplace in liquid-tight fashlon.

It is obvious that numerous changes may be made in the details set forthwithout departure from the essentials of the invention as defined in theclaims.

I claim as my invention 1. A container comprising a body,having anopening therein, a cap for said opening, one of saidparts having anparallel to the edge portion 0 the other part, and a securing strip ofsoft, annealed metal bent over and compressed upon the flange and edgeportion of said parts to secure said cap in place.

2. A container comprising a body having an opening therein, a cap forsaid opening,

one of said parts having an edge flange par-f allel to the edge; portionof the other part and one of "said parts being formed of 'fibrous,,-yielding material, and a flexible stripof soft, non-elastic metal bentover and compressed upon the flange and edge portion of said parts tosecure said cap in place and form a tight joint between the same and thebody of said container.

3. A container comprising a body having an opening therein, a cap forsaid opening, one of said parts having an edge flange parallel to theedge portion of the other part, and a flexible strip formed of soft, an-

nealed metal and consisting of a series of connected loops bent over andcompressed upon the flange and edge portion of said parts to secure saidcap in place.

A. A container comprising a body having an opening therein, a cap forsaid opening, one of said parts having an edge flange parallel to theedge portion of the other part and said parts being formed of yielding,fibrous material, and a flexible strip of dge flange,

soft, annealed metal and consisting of a series of connected loops bentover and compressed upon the flange and edge portion of said parts tosecure said cap in place and form a tight oint between the same and thebody of said container.

5. In closures, the combination of a body portion open'at its end, a caphaving an outturned flange fitting within said opening, and a securingstrip formed of soft, nonelastic metal and consisting of a series ofconnected loops bent over and compressed upon said flange and the edgeof said body portion. i

6. In closures, the combination of a body portion at its end, a capformed of fibrous material and having an outturned flange fitting Withinsaid opening, and a detachable sealing strip of soft, non-elastic metalbent over and compressed upon said flange and the edge of said bodyportion to form a tight oint between the same.

7. In closures, the combination of a body portion open at its end, a caphaving an outturned flange fitting within said opening, said parts beingformed of fibrous material, and a detachable sealing strip of soft,nonelastic metal bent back and forth upon itself to form a plurality ofloops, said loops being bent over and compressed upon the flange of saidcap and the edge of said body portion and clamping the same together toform a tight joint.

8. In closures, the combination of a body portion open at its ends, acap having an outturnedflange fitting within said opening, one of. saidparts being formed of fibrous mater al, and a,cont1nuous, flexible,sealing strip of soft, non-elastic metal bent over and compressed uponthe edge of said body portion and the flange of said cap to secure thesame in place in moisture-tight fashion, said strip having an endportion extending inwardly over the face of said cap and adapted to begrasped to detach. said strip.

9. A flexible sealing strip disconnected at its ends and bent back andforth upon itself to form a plurality of loops, said loops being benttransversely to form a series of connectedU-shaped clamps adapted toembrace thc'overlapping edges of a container and its closure, said stripbeing formed of soft, non-elastic, annealed wire, whereby said U-shapedclamps are adapted to be contracted in applying said sealing strip andexpanded in removing the same without tending to recover the shape fromwhich they are forced in the application or'removal of the strip,substantially as described.
